Definitions

  • a second diameter is arranged between the inner peripheral surface and the first diameter, wherein a cross-sectional area of the die present on a second diameter is at most 80%, in particular at most 60%, preferably at most 40%, of the inner peripheral surface.
  • a further cross-sectional area is provided between the second diameter and the first diameter which is greater than the cross-sectional area present on the second diameter.
  • a plurality of centering surfaces are arranged on the first diameter, wherein the centering surfaces are arranged spaced apart along the circumferential direction.
  • at least three centering surfaces are provided, which are arranged spaced from each other along the circumferential direction.
  • the holding region is arranged in the radial direction between the inner circumferential surface and the first diameter.

Abstract

L'invention concerne une matrice (1) destinée à être disposée dans une presse (2), la matrice (1) s'étendant le long d'une direction axiale (3) entre deux côtés frontaux (4, 5) et formant une surface périphérique intérieure (6) entre les deux côtés frontaux (4, 5), la matrice (1) s'étendant à partir de la surface périphérique intérieure (6) le long d'une direction radiale (7) en direction d'une surface périphérique extérieure (8) et en direction d'au moins une surface de centrage (10) disposée sur un premier diamètre (9) dans la direction radiale (7) ; la matrice (1) comprenant une zone de pressage (11) de manière espacée des côtés frontaux (4, 5) et présentant, dans la région de la zone de pressage (11), une première rigidité maximale plus élevée au moins vis-à-vis de zones (12, 13) disposées sur les côtés frontaux, par rapport à une force de pressage (14) agissant dans la direction d'un vecteur normal (32) à la surface périphérique intérieure (6) ; la première rigidité maximale étant supérieure d'au moins 10 % à la deuxième rigidité minimale présente dans au moins l'une des zones (12, 13) disposées sur l'un des côtés frontaux (4, 5).
